What is Tris-Biphenyl Triazine?
Tris-Biphenyl Triazine (CAS 31274-51-8) is an organic UV absorber and light stabilizer used to protect materials from photodegradation. Also marketed as Tinosorb S Lite Aqua.
Where is Tris-Biphenyl Triazine used?
- Personal care: broad-spectrum UV protection, approved in multiple regulatory markets
- Coatings and polymers: extend service life
- Outdoor-exposed plastics, films and industrial coatings subject to UV stress
- Adhesives and sealants: prevent UV-induced yellowing and loss of bond integrity in construction and automotive applications
- Specialty polymer compounding: long-term colour stability and mechanical retention under UV exposure
- It absorbs UV radiation across both UVA and UVB ranges, preventing premature breakdown of polymers, coatings and cosmetic formulations.
Commercial specifications
- Technical-grade supply with defined purity specifications
